    * PROBLEM DESCRIPTION: This enhancement introduces TAS         *
    *                      failover capability for DAI, allowing   *
    *                      it to automatically switch to a backup  *

    * RECOMMENDATION: Apply the PTF for this APAR.                 *
    ****************************************************************
    DAI allows configuring multiple TASs in a failover
    configuration. In this configuration, multiple TASs run, with
    one acting as the primary server and the others acting as
    backup servers. This configuration helps minimize service
    disruption caused by TAS failures or other issues.
